The aim of this research is to fabricate Perovskite LEDs with beta-phase-induced ordered EML. The 5% ordered film shows improved efficiency and lifetime compared to the 0% beta-phase Perovskite LED. Paios was used to balance electron-hole mobilities for beta-phase samples, measured by MIS-CELIV and differential susceptance, which is argued to lead to a better charge balance factor and thus a higher EQE.
